Pig husbandry in a changing social and economic environment


Measures to improve animal welfare implemented by the Dutch pig sector do not have the desired effect on societal concerns about pig husbandry. The aim of this research was to estimate the effects of measures to improve animal welfare in sow husbandry (where pigs are being reproduced) in the Netherlands on animal welfare, farm income and citizens’ attitudes. Firstly, it is shown that citizens have negative attitudes toward sow husbandry with respect to animals, humans and the environment and conventional pig farmers only toward economic aspects, such as income. Tested animal welfare measures with a positive effect on farm income were not the most efficient measures when all mentioned effects were included. Thus a positive effect on animal welfare does not necessarily lead to an equivalent positive effect on citizens’ attitudes or a deterioration of farm income. That is why it is essential to integrate all these effects in the evaluation of animal welfare measures. 


  1. The pig sector needs to understand how citizens interpret and weigh moral values in order to understand citizens’ negative attitudes toward sow husbandry. (this thesis)
  2. Pig housing measures are the most efficient because they best take into account simultaneously the effects on animal welfare, farm income and citizens’ attitudes toward pig husbandry. (this thesis)
